2 SECTION II - INSTALLATION

2.1 GENERAL INFORMATION

2.1.1

This section of the manual will provide the needed information to successfully complete the installation of
your new NAV 2000 Navigation Receiver. Please read this section completely before proceeding with the
installation process. Although the NAV 2000 installation procedures are designed with the do-it-yourself in
mind, we at Val Avionics Ltd. strongly suggest that you seek the advice of a qualified avionics installation
facility before beginning this or any other installation project. Qualified avionics installation technicians
can offer good advice as to time-tested installation practices and techniques that can save you many hours
of time and frustration.

Scope

2.2 UNPACKING AND INSPECTION

Use care when unpacking the equipment. Inspect the unit and supplied parts for visual signs of damage
during shipment. Examine the unit for loose screws, dents, broken buttons and other signs of damage that
may have occurred during shipment. Verify the contents of the container with the list in section 1.5. If any
damaged or missing parts are discovered during the inspection save the shipping material and contact the
freight carrier to file a claim. If it is suspected that parts were omitted from the container please feel free to
contact Val Avionics Ltd., to acquire the missing items.

2.3 EQUIPMENT INSTALLATION PROCEDURES

2.3.1

Forced air cooling is not required for the NAV 2000 Navigation Receiver. However, when planning the
location for mounting, ensure adequate spacing from heat producing sources such as heating or defrosting
ducts.

2.3.2

The NAV 2000 mounting tray should be rigidly mounted in the avionics stack using the hardware provided
in the installation kit. Ensure that the mounting location will provide easy access and a clear view of the
equipment’s front panel from the pilot’s position. Ensure that the mounting position will provide adequate
clearance between the unit and the associated wire harness and the aircraft controls. Bracing at the rear of
the unit should be installed to ensure rigidity in the panel. Consult FAA Advisory Circular AC 43.13-2A
for acceptable practices and techniques.

2.3.3

Val Avionics Ltd. recommends that a factory fabricated wire harness (VPN 0751020) be used for the
installation of the NAV 2000 Navigation
receiver. Use of the factory fabricated wire harness will ensure proper operation of the NAV 2000,
reduction in the occurrence of interfering signals and ground loops, greatly reduced installation time, and
provide prolonged trouble-free performance of your new equipment. Contact Val Avionics Ltd. or your
local avionics distribution center for NAV 2000 Wire Harness ordering information.

Although strongly recommended, it is not required to use the factory fabricated wire harness when
installing the NAV 2000. A wiring harness can be fabricated in the field. Refer to appendix B of this
manual for a complete wiring diagram. The NAV 2000 is connected to the aircrafts avionics bus via a 2
AMP circuit breaker. All wires must be 22 AWG MIL-SPEC, unless otherwise noted in accordance with
current regulations. Two and three conductor shielded MIL-C-27500 or equivalent wire must be used
where indicated. Use AMP Contact Crimping Tool (AMP P/N 601966-1) with Positioning Tool (AMP P/N
601699-5) or equivalent to ensure good quality contacts. Refer to FAA Advisory Circular AC 43.13-2A for
acceptable practices and techniques.

2.3.4

NAV 2000 Installation

2.3.4.1 Mounting

The NAV 2000 is rigidly mounted in the aircrafts avionics stack. Once a location has been selected, a
visual inspection should be made of the area directly behind the panel which will be occupied by the NAV
2000 and harness assembly for obvious obstructions such as heater ducts, control cables, fuel and oil lines
or any other obstruction. Pay particular attention to the control yoke assembly. It should be moved to the
full limit of travel and verified that sufficient clearance exists prior to beginning installation. Most aircraft
instrument panels will already have existing radio mounting cutouts. If the location you have selected
requires that a mounting hole be cut, refer to Figure 3: Panel Cut Out on Page 15 for the mounting
template. Mark and cut the mounting holes as required.

Position the unit’s mounting tray in its upright position, and from the rear of the panel. With the unit held in
place, insert the two supplied 6-32 X 1/2” countersunk screws VPN 501053 from the front and tighten as
appropriate. The installing agency must fabricate and attach rear support brackets to the aircraft structure
behind instrument panel as appropriate to support the rear of the NAV 2000. Then, attach these brackets to
the provided attachment points on the rear of the unit with the supplied 6-32 1/4" truss head screws VPN

501063.

2.3.4.2 Antennas

One antenna is required for the NAV 2000 installation. A standard VOR/Localizer/Glide Slope antenna can
be used with the unit such as a COMANT CI-157 or equivalent. The most common location for the antenna
is on top of the vertical stabilizer. The VOR/Localizer/Glide Slope antenna can be coupled to the unit’s
NAV-in port directly.

V A L A V I O N I C S L T D

2.3.4.3 Audio

The NAV 2000 has one navigation audio output. Although the audio output levels of the receivers are
capable of driving a standard headset directly, it is strongly recommended that these audios be coupled to a
quality audio selector panel. For complete details, refer to the interconnect wiring diagrams in Appendix B.

2.4 POST INSTALLATION CHECK

2.4.1

Refer to section three of this manual. Using a calibrated VOR, Localizer and Glide Slope signals, check all
functions of the NAV 2000 for proper operation. Check the operational functions of other equipment
installed in the aircraft in accordance with the individual manufacture’s operation manuals to insure that no
cross interference exists as a result of this installation.

2.4.2

Verify that the wiring is bundled away from all controls and that no part of the installation interferes with
the movement of the aircraft controls. Move all of the aircraft controls through their full range of
movement while visually verifying that the installation does not mechanically interfere with the control
movement. Verify that the wiring harnesses are properly secured to the aircraft structure in accordance with
accepted practices as described in AC 43.13 and that adequate strain relief and service loops have been
provided. Ensure that there are no kinks or sharp bends in the wire harnesses. Verify that the wire bundles
are not exposed to any sharp or abrasive surfaces. Complete log book entries, weight and balance
computations and other documentations as required.
